Pedometer with game mode

ABSTRACT

An object of the present invention is to provide a new pedometer with game mode which can be used as a game by a child to get some exercise such as walking and/or running without reluctance. When a vibration is detected by a vibration detector, the count values of a step-number counter and an integrating counter are incremented, and thereby a display state of a character displayed on an LCD is varied based on the count values of step-number counter and/or the integrating counter.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to pedometers with game mode and, more specifically, to a pedometer with game mode which varies an image of a character or a scene displayed thereon for a game based on its count value. Thus, the pedometer can be used as a game with enjoyment even by a child.

[0003] 2. Description of the Background Art

[0004] It is to be noted that recently, the number of playgrounds for children decreases in towns, causing the children who do not get enough exercise to increase in number. Resultantly, it becomes a social problem that the number of fat children and the children suffering from symptoms of geriatric-diseases is growing. It is well known that walking is most effective for solving the shortage of exercises. However, walking itself is too monotonous and weary exercise even for an adult to continue, much more for a child.

[0005] To encourage a person for overcoming such monotony and weariness in walking, provided are conventional pedometers which simply indicate the number of steps the walker has taken. Conventional pedometers are simply used to count the number of steps when a person takes a walk for the sake of health, and to indicate the counted step numbers. Some of the conventional pedometers have auxiliary modes such as calculating the consumed calorie of the walker based on step-number data. However conventional pedometers, even with such auxiliary mode, lack every entertainment elements, so that no child may take pleasure in using it. The children might not be motivated to walk or run by the conventional pedometers for adults. For this reason, a pedometer capable of being used with enjoyment even by a child is desired.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0084] In FIG. 1, an appearance of a pedometer with game mode (hereinafter, referred to as a “pedometer”) according to an embodiment of the present invention is shown. The pedometer 10 includes a main screen 12 mainly constructed by a Liquid Crystal Display (hereinafter, referred to as an “LCD 12”) located on the front-side surface of a housing 11, and a control section 13 formed below the LCD 12.

[0085] The LCD 12 is a dot-matrix type display, and is provided with a game image display screen 121 in a large area thereof. The game image display screen 121 (sic section) is used for displaying a character or a figure. The LCD 12 is further provided with a clock image display section 122 above the game image display screen 121 for displaying time, and a step-number image display section 123 below the game image display screen 121 for displaying the number of steps. More preferably, in appropriate positions around the game image display screen 121, provided are icons 124, 125, 126 and the like which are manipulated by a user to designate different input modes.

[0086] For example, the icon 124 is a mark displayed on the screen to represent “a set time information” with which the user can set an time information and input that set time information into the pedometer 10. Similarly, the icon 125 is a mark representing “an alarm time” for the user to set an alarm time. The icon 126 is a mark representing “a game mode” for the user to select a game mode in which the user (a player) can play a game independently of step-number data and/or time data.

[0087] The control section 13 includes a reset button 131, a start button 132, a direction-instructing switch 133 for giving instructions on selection of an icon or transfer of a character in the game mode, and behavior switches 134 and 135 for giving instructions on the behavior of the character.

[0088] In addition, in the housing 11 is accommodated an electric circuit substrate containing a one-chip microcomputer and various electronic components shown in FIG. 2 which will be described soon later. Moreover, on the back-side of the housing 11 is formed a hook for hooking the pedometer on a user's belt or the like to be attached to the body, in the same manner as in conventional pedometers.

[0089] In FIG. 2, a block diagram of an electric circuit substrate incorporated in the pedometer 10 is shown. A circuit EC includes a one-chip microcomputer 20. The one-chip microcomputer 20 is comprised of a CPU core 21, a read only memory (ROM) 22, and random-access memory (RAM) 23. ROM 22 stores the following programs in a non-revisable mode. Those programs, for example, includes a clock display program, an alarm generation program, a step number calculating and display program, a step number accumulation, and a game program for displaying images based on various information including present time, step-number, accumulated-step-number, and the like.

[0090] The game program contains, for example, data of characters shown in FIGS. 5, 6 and 8 each displayed in the game mode, and a program whose operation flow charts are shown in FIGS. 7, 9 and 10 for controlling the display of those characters' images. Further, the game program may be a program for varying the displayed images representing the game state independently of the present time or the step number. For example, a program for a mini-game such as a slot machine and a fortunetelling game are also possible.

[0091] RAM 23 is used as a working memory or a register for temporarily storing various data which is required when the pedometer 10 is used as a clock, a pedometer, or a game machine. The details of RAM 23 will be described later with reference to FIG. 3.

[0092] To the CPU core 21 are connected each of switches or buttons 131 to 135 included in the control section 13, and a vibration detector 24. In addition, to the CPU core 21 is connected as required a hardware reset switch 25 in order for the user to initial clear (cold reset) RAM 23 and display RAM 26 at the start of usage of the pedometer 10. The CPU core 21 performs processing according to the programs in response to the input from the switches and the vibration detector 24, and further generates the display data for varying the images displayed on the LCD 12. The display data processed by the CPU 21 is outputted to the display RAM 26 to be temporarily stored, and then supplied through an LCD driver 27 for the LCD 12 to be displayed.

[0093] Next, specifically described is a function of the CPU core 21. The CPU core 21 clocks a present time according to each program stored in ROM 22, and also obtains the number of steps by counting the output of the vibration detector 24. The CPU core 21 further generates the display data for varying the character images displayed on the game display screen 121 to represent predetermined game state based on the present time data and/or the step-number data. Note that the game state represented by character images is referred to as “display state” hereinafter. In the case where the display state is varied based on the count value of a step-number counter 23 b (FIG. 3), the user can realize a desired display state by shaking the pedometer 10 by hand to cause vibrations and thereby incrementing the counter. On the other hand, in the case where the display state is varied based on an integrating counter 23 c (FIG. 3), since the user cannot always grasp the count value, unpredictable or random fashioned variations of the display state can be realized, which means variations depending on indefinite factors which are effective for a game can be acquired. That is, the count value of the integrating counter 23 c can be used in place of random number data ROM generating random number data for the game.

[0094] Used as conditions or factors determining the variations of the game display state is information on the basis of more than one or two of the following information; the step number information, the integrated-step-number information, and the present time information. As variations of the display state regarding the game, it is thought that the character or a virtual pet behaves or makes motions and gestures according to time. Those behaves or gestures may be “getting up”, “brushing its teeth”, “having a meal”, “walking”, “running”, “studying”, “playing a ball”, “sleeping”, and the like, for example. The character or virtual pet is a living thing such as a person, a dog, a cat and the like, or an imaginary creature like a monster. It is possible to enhance the game features by varying the display state of the character so that the user can bring it up as the other self of the user or a pet. Furthermore, it is possible to set the behavior of the character corresponding to a schedule for a day of the user to vary the behavior pattern based on the step-number information or the integrated-step-number information.

[0095] With reference to FIG. 3, a memory map of working RAM 23 and display RAM 26 is described. Working RAM 23 includes a counter area 231 and a register area 232. The counter area 231 uses a plurality of registers as counters, which includes, for example, a clock counter 23 a for clocking the present time, the step-number counter 23 b and the integrating counter 23 c. The clock counter 23 a clocks the present time on the basis of a reference clock 28. The step-number counter 23 b is reset by the user's operation of pushing a reset button 131, and counts the number of steps after the reset by counting pulses supplied by the vibration detector 24. The integrating counter 23 c integrates or accumulates the step number taken from the start of usage of the pedometer 10 to present, thereby obtaining the integrated value of the step number. The integrated value or accumulated value is used in all figures or partial figures when random data is required to control the game.

[0096] More preferably, the counter area 231 includes a watt counter (game counter) 23 d for incrementing its count value by one each time the step-number counter 23 b or the integrating counter 23 c increments its count value by a predetermined value (for example, twenty steps). The count value of the watt counter (game counter) 23 d is used as a value for playing a mini-game or a value which can be given to the character as a present in order to please the character. For example, when electricity or energy is given as a present, the unit of the count value is referred to as “watt”).

[0097] The register area 232 is composed of a plurality of registers, which includes, for example, an alarm time register 23 e and a backup register 23 f, and in addition, a game-play-number register 23 g as required. The alarm time register 23 e is also used to store the set alarm time. The backup register 23 f is used to store and keep the step-number information of a day during twenty-four hours in the next day in the case of controlling the game with using the step-number information of the previous day (for example, in the case of producing such a display that the virtual pet is still tired when the amount of walks taken in the previous day is large). Display RAM 26 has a storage area corresponding to the number of dots in rows and columns of the LCD 12.

[0098] With reference to FIG. 4, the vibration detector 24 is described. The vibration detector 24 includes a substrate 240, a pendulum 241, and a lead switch 242. The pendulum 241 have an elongated spring 243 fixed on the substrate 240 in a manner so that the spring 243 can swing in a direction substantially perpendicular to the main plane of the substrate 240. The pendulum 241 further have a magnet 244 fixed at free end of the spring 240, and is able to reciprocate in the same direction in which the spring 243 swings. A lead switch 242 is provided in the position to which the magnet 244 moves close to the substrate 240. Each time a vibration is added to the pedometer 10 when the user putting on the pedometer 10 walks or runs, the magnetic 244 vertically reciprocates. Resultantly, the lead switch 242 is turned on/off by magnetism of the magnet 244. In this way, a pulse is generated for each step.

[0099] With reference to FIGS. 5 and 6, an example of character image displayed according to the game state displays on the pedometer 10 is described. The figures particularly show the case that is a person who is an imaginary friend of the user, and behaves in accordance with user's way of life in a day. However, the character or virtual pet is not restricted to the above, but may be an animal such as a dog and a cat, or a monster, an imaginary cute creature, and the like.

[0100] In FIG. 5, the game character's or virtual pet's images corresponding to each of display state from the morning to the noon are shown. Image Ia represents that the game character or the virtual pet wakes up in the “morning”,

[0101] image Ib represents that the game character or the virtual pet “brushes” his or her tooth,

[0102] image Ic represents that the game character or the virtual pet “munches” the breakfast,

[0103] images Id and Id1 represent that the game character of the virtual pet “studies” n and takes exercises speaking “One, Two, Three, Four”, respectively, and image Ie represents that the character or the virtual pet “munches” the lunch.

[0104] In FIG. 6, the game character's or virtual pet's images corresponding to each of display state from the noon to the night are shown. Image If, If1, and If2 represent that the game character or the virtual pet plays the guitar, swims, and plays soccer, respectively,

[0105] Image Ig represents that the game character or the virtual pet “munches” the supper,

[0106] images Ih, Ih1, and Ih2 represent that the game character or the virtual pet watches TV, plays with a radio control car, and operates a computer, respectively.

[0107] Images Ii and Ii1 represent that the game character of the virtual pet takes a shower and takes a bath, respectively, and

[0108] Image Ij represents that the game character or the virtual pet sleeps.

[0109] With reference to FIG. 7, a main operation performed by the pedometer 10 according to the present invention is described. To start the operation of the pedometer 10, the user puts in a battery therein, first.

[0110] At step S1, the images of icons 124, 125 and 126 described with reference to FIG. 1 are displayed on the LCD 12. Then, an input mode screen is displayed on the LCD 12. At this time, the user selects the icon 124 by operating the direction switch 133, thereby selecting a present time input mode. Then, the user operates the direction switch 133 and switches 134 and 135 to input the present time. Further, the user can input an alarm time as necessary.

[0111] At step S2, processing before step-number count operation are performed, for example, setting the input present time in the clock counter 23 a, resetting the step-number counter 23 b, and the like.

[0112] At step S3, step-number count processing are performed. That is, the processing increments the step-number counter 23 b and the integrating counter 23 c each time a pulse is inputted from the vibration detector 24.

[0113] At step S4, the behavior or gestures of the game character or the virtual pet corresponding to time based on the time information is displayed. Specifically, as shown in FIGS. 5 and 6, images or illustrations for displaying behavior patterns which the user is assumed to follow from when he or she gets up in the morning to when he or she goes to bed at night are sequentially displayed at the corresponding time.

[0114] The images like the following are displayed in the game-screen-display area 12 according to time: the image Ia (FIG. 5) of getting up at 6 a.m., the image Ib (FIG. 5) of brushing teeth, the image Ic (FIG. 5) of having breakfast, the images Id1 and Id2 (FIG. 5) of studying, the image Ic (FIG. 5) of having lunch, the images If, If1, and If2 (FIG. 6) of playing music, the image Ig (FIG. 6) of having supper, the images Ih, Ih1, and Ih2 (FIG. 6) of relaxing, the image of taking a shower Ii (FIG. 6) and the image Ii1 (FIG. 6) taking a bath, and the image Ij (FIG. 6) of sleeping, and the like. In addition to the above images, the present time clocked by the clock counter 23 a is displayed on the clock display portion 122 and the step number counted by the step-number counter 23 b is displayed on the step-number display portion 123.

[0115] At step S5, performed is control to vary the display state of the character based on the step-number information. For example, during a time when the image Id (FIG. 5) of studying is displayed (at 9 a.m. to noon), in the case where the count value of the step-number counter 23 b is more than or equal to the step number taken in a daily life by a predetermined number, the image Id1 (FIG. 5) of playing sports is displayed in place of the image Id of FIG. 5.

[0116] During a time when the image If (FIG. 6) of playing music is displayed (at 1 p.m. to 6 p.m.), in the case where the count value of the step-number counter 23 b is more than or equal to the step number taken in the daily life by a predetermined number, the image If1 or If2 (FIG. 6) of playing sports such as swimming and soccer is displayed in place of the image If (FIG. 6). Similarly, during the time for relaxing (at 6:30 p.m. to 8 p.m.), depending on the amount of step number, displayed is the image Ih (FIG. 6) of watching TV, the image Ih1 (FIG. 6) of playing with a radio-controlled car, or the image Ih2 (FIG. 6) of operating a personal computer.

[0117] In the above way, the image of the character is varied according to time and the behavior or gestures of the character is varied based on the amount of walks, so that even a child user finds it amusing to walk or get exercise with putting on the pedometer 10. Therefore, it is possible to realize a pedometer capable of encouraging a child in the use.

[0118] When using the count value of the integrating counter 23 c (that is, the accumulated step number) in place of the count value of the step-number counter 23 b (that is, the number of steps) as the step-number information which is a factor to vary the display state of the character, if the user increases the count value by shaking the pedometer 10 by hand without actually walking, he/she does not know the integrated step number (or the accumulated step number) because the number is not always displayed. Thereby the display state can be varied based on data which has irregular or random properties.

[0119] In order to enhance the random properties when varying the display state based on the integrated step number, the result of calculation such as an added value of a plurality of digits of the integrated-step-number information can be used. Moreover, it may be interesting that the step number of the previous day is stored in the backup register 23 f in advance, when the step number exceeds a given number, the time to display the image of getting up in the morning is delayed, or such an image is displayed as the character gives a yawn or looks tired as if it is still tired when it gets up.

[0120] At step S6, performed is update processing of various parameters associated with the growth of the character. In the update processing, the program is set so as to be different based on time passage information or day passage information, and in addition, depending on which predetermined ranks the accumulated step number belongs to, thereby making it possible to make the pedometer more amusing.

[0121] At step S7, the time information is updated each time a unit time (for example, a second or a minute) is passed. Then, the operation at step S3 to S7 is repeated.

[0122] Next, a more detailed embodiment will be described.

[0123] In FIG. 8, an example of game displays according to another embodiment of the present invention is shown. In this example, the image is varied in accordance with the increase of the step number during the time of studying (at 9 a.m. to noon). For example, when there is little change in the step number within a given period (for example, five minutes), the same image Id of studying in FIG. 5 keeps being displayed. While, when there is an increase equivalent to a walk, equivalent to the image of walking, the image Id2 (FIG. 8) of walking is displayed, or when there is an increase equivalent to the amount of exercise larger than the walk, the image Id3 (FIG. 8) of running is displayed.

[0124] Then, in the case where the increase in the step number stops in the middle of displaying the image of running, which means that the user stops walking, the image Id4 (FIG. 8) of stopping and gasping for breath is displayed. Moreover, in the case where there is no change in the step number for more than a given period, the image Id5 (FIG. 8) of crouching down in the corner of a room (or crooked expression) is displayed, thereby encouraging the user to get more exercise.

[0125] FIGS. 9 to 10 are flow charts for describing another embodiment of the pedometer of the present invention. Described below is detailed operation of the pedometer 10, referring to FIGS. 5, 6, and 8 to 10.

[0126] After the user put in a battery to turn the power on, the CPU core 21 starts the following operation based on the program stored in ROM 22.

[0127] At step S11, all areas in working RAM 23 and display RAM 26 are initial reset in response to a press of the hardware reset switch 25, thereby preventing an error operation caused by undesirable data stored in the areas before the power-on.

[0128] At step S12, an initial input screen or the icons as shown in FIG. 1 are displayed.

[0129] At step S13, the operation is in wait state until any input is performed. At this time, when the user operates the switches 131 to 135 to specify an input mode by key operation or icon designation, the specification is judged at step S13 and the procedure advances to step S14.

[0130] It is judged at step S14 whether the specification is for clock setting or not. When judged it is for clock setting, the information inputted by key operation is set in the clock counter 23 a as a present time at step S15. On the other hand, when judged otherwise, it is judged at step S16 whether the specification is for alarm setting or not. When judged it is for alarm setting, the information inputted by key operation is set in the alarm time register 23 e as an alarm time at step S17.

[0131] When judged it is not for alarm setting at above step S16, it is judged at step S18 whether the reset button 131 is pressed (or on) or not. When judged the reset button 131 is pressed, the count value of the step-number counter 23 b is set in the backup register 23 f at step S19 and then the step-number counter 23 b is reset at step S20. Instead of pressing the reset button 131, the user may set the count value of the step-number counter 23 b in the backup register 23 f as explained below in detail at step S37 at the end of a day (or at the beginning of a day at midnight) as.

[0132] On the other hand, when judged at step S18 that the reset button 131 is not pressed, it is judged at step S21 whether the specification is for displaying the count value of the integrating counter 23 c or not. When judged positively, the count value of the integrating counter 23 c is displayed on the step-number display portion 123 for a given period at step S22. After step S15, S17, S20 and S22 or after the specification is judged not for displaying the count value of the integrating counter 23 c at step S21, the procedure advances to step S23.

[0133] At step S23, displayed on the game display screen 121 is the image in relation to time and depending on the step-number information and the like (for example, any one of images Ia to Ij in FIGS. 5 and 6), based on the present time and the count value of the step-number counter 23 b (the number of steps) and/or the count value of the integrating counter 23 c (the integrated value).

[0134] It is judged at step S24 whether a vibration detecting signal is outputted from the vibration detector 24. When judged positively, the count values of the step-number counter 23 b and the integrating counter 23 c are respectively incremented (by one) at step S25. While, when judged no vibration is detected, it is judged at step S26 whether the vibration detecting signal is not outputted for more than a given period or not. In the case where it is judged no vibration is detected for more than the given period, the image for such case (for example, Id5 in FIG. 8 for the period during 9 a.m. to noon) is displayed at step S27.

[0135] At step S28, it is judged whether the amount of changes in the count value of the step-number counter 23 b per a unit time (for example, five minutes) is more than or equal to a given value equivalent to the image of running. When it is judged NO meaning that the user is walking, then the procedure advances to step s29.

[0136] At step S29, the image of walking (for example, image Id2 in FIG. 8) is displayed.

[0137] At step S30, it is judged whether the amount of change in the count value of the step-number counter 23 b is 0 or not. When judged negatively, the procedure returns to step S28, S29 and S30 again. When judged the amount of change is 0, the procedure advances to step S34 described later.

[0138] On the other hand, in the case where the amount of changes is more than or equal to the given value at step S28, the image showing such case (for example, image Id3 in FIG. 8) is displayed at step S31.

[0139] At step S32, then, it is judged whether the amount of changes in the count value of the step-number counter 23 b is 0 or not. If the user is running, the amount of changes is judged not to be 0 and the procedure returns to step S28, S31 and S32 again. While, if the user stands or stops running because of fatigue, the amount of changes is judged to be 0. Thus, it is detected that the state in which the amount of changes in the count value is more than or equal to the given value (that is, the running state ) ends. Then, the procedure advances to step S33

[0140] At step S33, the image of being tired and gasping for breath (image Id4 in FIG. 8) is displayed as a state after running.

[0141] At step S34, it is judged whether the display state is varied on the count value of the integrating counter 23 c. When judged positively, the behavior or gestures of the character is varied based on the count value of the integrating counter 23 c at step S35.

[0142] In this way, the display state of the virtual pet is varied based on the number of steps or the integrated value. Therefore, the more interesting to the user the varied image is, the more useful the pedometer 10 is for solving lack of exercise of the user by motivating and encouraging the user to get exercise.

[0143] At step S36, It is judged whether it is the end of a day (it is at midnight) or not. When it is not the end of the day, the procedure returns to step S23 and repeats the above operation. When judged it is the end of the day, the procedure advances to step S37.

[0144] At step S37, the step-number information for the previous day counted by the step-number counter 23 b is temporarily stored in the backup register 23f. The step-number information for the previous day is used to vary the time to wake up in the next morning for the character and the expression of the character after getting up (the expression of a tired face, gestures of having a sore foot and the like), based on the fatigue of the character in the previous day.

[0145] With reference to FIGS. 11, 12, 13, and 14, a pedometer with game mode according to still another embodiment of the present invention is described bellow. Although the above embodiments describe the case where the behavior of the game character or the virtual pet is varied based on the step-number information, the present invention is not limited to such display and can be applied to various game displays. For example, it is assumed here that a game content conventionally known is used and allowed to be played one time for a given number of steps. According to this embodiment, the pedometer with game mode further includes a third counter which counts watt counter, as specifically described below.

[0146]FIG. 11 is a flow chart similar to FIG. 7, but three steps S3 a, S5 a and S5 b with respect to watt are added thereto. Specifically, step S3 a for watt counting process is inserted between step S3 and step S4, and step S5 a for judgment for using watt and step S5 b for character display control based on used watt are inserted between step S5 and step S6 in FIG. 7. Since the operation is the same as those already described with the FIG. 7, except these additionally inserted steps S3 a, S5 a and S5 b, descriptions are made only for these added steps.

[0147] At step S3 a, the game counter 23 d for functioning as a watt counter included the counter area 132 increments its count value by one each time the step-number counter 23 b or the integrating counter 23 c increments its count value by a predetermined value (for example, twenty steps). The count value of the game counter (watt counter) 23 d is used as a value for playing a mini-game or a value which can be given to the character as a present in order to please the character . For example, when electricity or energy is given as a present, the unit of the count value is referred to as “watt”. In FIGS. 13A, 13B, 13C, 13D, and 13E, examples of images showing that the virtual pet is pleased with the presented watt are shown.

[0148] At step S5 a, it is judged whether the user will use watt obtained at step S3 a for present or mini-game, or not. When it is judged NO, the procedure advances to step S6. However, when it is judged YES, the procedure advances to the step S5 b.

[0149] At step S5 b, the mini-game becomes available or game character's (virtual pet's) image is displayed based on the consumed watt.

[0150]FIG. 12 is a flowchart similar to FIG. 10, but a sub-routine with respect to watt is added thereto. Specifically, step S40 which is a sub routine for watt count processing is inserted between steps S25 and S28 in FIG. 10. The details of sub routine S40 is described with reference to FIG. 14 bellow.

[0151] At step S41, it is judged whether the count value of step-number counter 23 b is not less than a predetermined value, fore example twenty. It is judged YES, the procedure advances to step S42, where a value of watt counter is incremented by one per each of -predetermined step-number which is twenty. On the other hand, when it is judged NO, the procedure advances to step S43.

[0152] At step S43, it is judged whether the user will use watt obtained at step S42, or not. When it is judged NO, the procedure advances to step S28 of FIG. 12. However, when it is judged YES, the procedure advances to step S48.

[0153] At step S48, it is judged whether the watt shall be used for the mini-game or not. When it is judged YES, the procedure advances to step S46.

[0154] At step S46, the watt value corresponding to the mini-game is subtracted from the count value of watt counter, and the user enjoys the mini-game.

[0155] At step S48, it is judged whether the mini-game results in increase of watt value or not. When it is judged “NO”, the procedure advances to step S28 of FIG. 12. On the other hand, when it is judged “YES”, the procedure advances to step S47, where the value of watt counter is increased by what determined by the result of mini-game. Then, the procedure advances to step S28 of FIG. 12.

[0156] However, when it is judged “NO” at step S44, the procedure advances to step S48, where it is judged whether the user gave watt to the virtual pet as a present, or not. When it is judged “NO”, the procedure advances to step S28 of FIG. 12. On the other hand, it is judged “YES”, the procedure advance to step S49, where the user determines to consume how much watt value as a present.

[0157] At step S50, according to the consumed watt value presented to the virtual pet, the image of pleased virtual pet is displayed.

[0158] At step S51, the friendships with the virtual pet is increased according to the consumed watt.

[0159] At step S52, the consumed watt is subtracted from the count value of watt gage, and then the procedure advances to step S28 of FIG. 12.

[0160] A game-play-number register 23 g is provided in the register area 232. Then, in the state where the user uses the pedometer 10 for counting the number of steps, the game-play-number register 23 g stores value incremented by one each time the count value of the step-number counter 23 b is incremented by the given number (500). When the user selects a game mode with an icon after walking or getting exercise, in response to the press of the game-start switch 132, the game operation is activated. Then, the image for the game is displayed and varied according to the user's operation of the switches 131 to 135 while the game-play-number register 23 g stores the value of one or more.

[0161] Thus, the step-number information is used as information for permitting game play, which leads to that the user gets more exercise in order to secure the number for game-play. Accordingly, it is possible to prevent such a problem that the user only plays the game without getting exercise.

[0162] In addition to the above, the step-number information or the integrated-step-number information can be used as information about game processing in various ways. Therefore, it is possible to realize a pedometer which can be used with enjoyment even in the case that the user is a child.
